**For this guide I recommend having achievements snapped so you can track when an episode counts to your tally.**
Once you find an episode that expires within the next 7 days. Load up and play the episode. Once the advertisement has finished playing, watch a few seconds of the episode, then you can fast forward towards the end of the episode.
I would then watch the last few second to ensure it counted.
I have not been able to confirm if you can watch the same episode over again to add to the tally.
